Fat Princess is primarily a one to thirty-two player game with the basic goal of collecting the Princess, bringing her back to the team's base, and then protecting her. The players collect food for the enemy's princess which makes her heavier and therefore harder to carry. The game contains six character classes (The Villager, The Worker, The Mage, The Ranger, The Priest, and The Warrior) each of which helps to make the team's task of capturing the princess easier.
